[htdig] Length limit of "words" attribute

[pyp]

Hi,   I run htsearch bu command line, so i have to specify the value of the "words" attribute in the command :   ./htsearch words=test   I wonder where is the limit of the length of this attribute. I mean, i tried with :   ./htsearch words=test1%20or%20test2%20or%20test3%20or%20test4%20or%20test5%20or%20test6%20or%20test7%20or%20test8 (i dont remember the exact length i tried), and i got the message "Word too long".   Where should I search to modify this parameter if it is possible?
